Hi !

Could anyone post worked sample of code for creation capture group for mixer
?

When I trying to explore AC’97 elements with ‘amixer’ tool I obtain next
scheme:

CD (io) |-> CD Volume → CD Mute ->OutAccu
|-> Input MUX

Is this correct or not ? May I use only mux elements for input source select
? Or may I to use the sw elements ?

BTW: How to obtain AC’97 codec ID from my another sound card ? Is this
possible ? Card is Vortex 8820, but mixer wrote that I have CTxxxx codec,
but I have TriTech xxxx codec (seen on card) ? Somewhere I heard that
TriTech is subdivision of Creative is this correct ?

Thanks !
